TalkTalk investigating data breach after hacker claims theft of customer data
A hacker claims to be selling the data of 18.8 million TalkTalk customers, but the telecoms giant says this figure is ‘significantly overstated’
In a statement to TechCrunch, TalkTalk spokesperson Liz Holloway confirmed the company is investigating the data breach, but said the 18.8 million figure claimed by the hacker is “wholly inaccurate and very significantly overstated.” “As part of our regular security monitoring, given our ongoing focus on protecting customers’ personal data, we were made aware of unexpected access to, and misuse of, one of our third-party suppliers’ systems,” Holloway told TechCrunch. Holloway declined to name the third-party supplier, but screenshots shared by b0nd suggest the data was stolen from CSG’s Ascendon platform, which TalkTalk uses for subscription management.
